Radiation shielding
Density and atomic number make lead the standard absorber, as sheet and brick.
HomeProduct categoriesNon-ferrous metals
Refined pure lead ingot available in four purity grades.
Density and atomic number make lead the standard absorber, as sheet and brick.
Grids, plates and terminals, by far the largest single use of refined lead.
Extruded as a seamless, moisture-proof sheath on submarine and oil-filled cable.
Cast and swaged into shot and cores, where density does the work.
Tin-lead solders, still specified in work that is exempt from lead-free rules.
